<span>The area to be determined is a segment of the circle.

Since central angle is 120 degrees and 120/360 = 1/3
area of sector of circle is (1/3)*36pi = 12pi
For the area of triangle, you can split it into 2 30-60-90 right triangles with sides 3:3sqrt3:6
thus base of triangle is 6sqrt3 and height is 3

Area = 1/2 * 3* 6sqrt3 = 9sqrt3 -->
segment area = 12pi - 9sqrt3</span>

The area to be determined is a segment of the circle.

Since central angle is 120 degrees and 120/360 = 1/3

area of sector of circle is (1/3)*36pi = 12pi

For the area of triangle, you can split it into 2 30-60-90 right triangles with sides 3:3sqrt3:6

thus base of triangle is 6sqrt3 and height is 3

Area = 1/2 * 3* 6sqrt3 = 9sqrt3 -->

segment area = 12pi - 9sqrt3

I just did this so I know it's correct.

the Hamilton eighth-grader took a trip to Myrtle beach. They drove a speed of 60 miles per hour. The trip was 570 miles. Write a
Leni [432]

Answer:

9.5 hours

Step-by-step explanation:

Your general equation is this:

y = mh + b

There is no b value because there is no starting value of miles.

y is the total number of miles driven. m is the amount of miles per hour. h is the number of hours.

570 = 60h

To find h, divide both sides by 60.

h = 9.5 hours

A courtyard has three walls with widths
wariber [46]

Using the greatest common factor, it is found that the greatest dimensions each tile can have is of 3 feet.

---------------------------

  • The widths of the walls are of <u>27 feet, 18 feet and 30 feet.</u>
  • <u>The tiles must fit the width of each wall</u>, thus, the greatest dimension they can have is the greatest common factor of 27, 18 and 30.

To find their greatest common factor, these numbers must be factored into prime factors simultaneously, that is, only being divided by numbers of which all three are divisible, thus:

27 - 18 - 30|3

9 - 6 - 10

No numbers by which all of 9, 6 and 10 are divisible, thus, gcf(27,18,30) = 3 and the greatest dimensions each tile can have is of 3 feet.
